I Made a Living, Glass Bedding "Pencil Barreled", Weatherby's, Mausers and Rem 700's, from, the 1970's thru 1992 at, $180 to $200, a Pop.
I would make, a Pyramid in the barrel Channel with a triangular bit, Dremel tool ( Room for, lots of Glass ), Drill a Few angled Holes, fill with, Brownell's AcraGlass and use, a Few Pounds of "UP-ward Thrust" on the underside of, barrel ( yup, a Big, consistent, "Pressure Point" ).
Guys Hunted, all over the Globe with NO, POI "Shifting",.. good Group's, in the Day, was about, 1 MOA.
Nowaday's, I bed action, Lug, Tang and about, 1.5 Inches of the Bbl's "Shank portion" then, free float.
But we HAVE, Better Quality Barrels, Today !
